WRAPPER-MAKING- MACHINE.

Application filed January 9, 1922. Serial No. 527,819.

My invention relates to wrapper making machines and particularly to a machine for making tubular corrugated wrappers for holding and protecting incandescent lamps and other articles.

The object of my invention is to produce a simple, practical curately accomplished.

- tional view of The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the. conclu-- sionhereof.

In the drawings: Fig. 1 is a plan view of my improved machine.

Fig. 11- 1s 8 is a side a plan view of lengthsafter slitting thereof into sections. Fig. 12 is an end elevational view of the finished wrapper or carton.

The machine comprises the unit A which takes care of the printing, folding, gluing and propulsion of the paper web of which wrappers are made, the mechanism B which provides for power transmission to various operating parts, the mechanism C for out- 'mechanism D 'ting the folded -web into lengths, and the which t ke me i ther s and efiicient machinewhich at one end receives a strip of paper ,disk 10 engages therewith.

the in-folding whereby the work is ac-" thereof. Fig. 3 is an enlarged- "ti'lbe. During travel the gluing mechanism,

slitting of the lengths and the corrugating thereof.

The unit A has the supporting framework 1 'jacent which is the printing roll- 5 which is secured on the shaft 6. The paper then travels around the idlerrollers 7 and 8 and thence around the roll 9 where the gluing The paper then travels around the spaced apart guidewheels 11 and 12 which are spaced apart laterally and by which it is guided to the folding mechanism 7. This folding mechanism comprises the folding rails 13 and 1a which are convergent away from the wheels-11 and 12 and at their outer ends 'have'respectively wings 15 and 16. These rails rise from a table 17 on which the paper travels after leaving the wheels 11 and 12. The paper is held on this table by the presser 18 which is arranged between the rails 13, 14

and is supported from the lower end of a shoe 19 which is suspendedfrom the cross bar 20 on the standards '21 on frame 1. Wheels 11 and 12 are also mounted on standards 21. The point 19'- of the shoe guides the paper from wheels 11, 12 into the space between the tongue 18 and table 17 the tongue being spaced away from the folding railsand its sides converging forwardly, so that as the strip of paper portions will be deflected upwardly. When the strip reaches 16, the upwardly deflected side margins of the paper will he curled inwardly with one edge slightly overlapping the other, as shown in Fig. 10, the strip emerging from the form of a flattened of the strip through the disk 10 applies glue along one edge thereof and this glued section becomes the overlapping section a which is then glued to the underlying margin at b (Fig. 10). strip, it passes between the upper and lower presser and feeding press the overlapping edges together so that the glue will rigidly secure these edges to-' gether. These rolls 22, 23 are supported at the inner end of the framework 1 in the bearing structure 24'. At the mechanism B the folding wings in travels its side' the folding wings 15 and V After folding of the rolls 22 and 23 which i the upper and lower rolls 46 and 47.

- its rear end the of the machine, is provided suitable variable speed driving and transmission mechanism.

.The mechanism shown comprises the frame 25 and connected at their ends respectively with the pulley disks 36, 37 and 38, 39, which disks are respectively slidable on theshafts 26 and 27. By means of a screw-rod 40, the levers are swun so as to vary the radius of engagement wit of the belt 41,any s eed of transmission being thus readily o 'tained between the driving shaft 26 and the counter-shaft 27. At its end the counter-shaft has the belt pulley .42 which is connected with the belt pulley 43 by belt 44, the pulley 43 being (on the section G of the machine. The mechanism illustrated is that commonly known as the Reeves transmission, but it will be understood that any suitable variablespeed mechanism may be used.

The flattened paper tube travels from the machine unit A to the cutting mechanism C along the table or guide 45 which terminates at the. cuttingmechanism which comprises The upper. roll 46 is provided with a knife-bar 48 and the lower roll with a cooperating bar 49. These rolls are driven atdiiferent relative s eeds so that thebars 48 and 49 will perio ically register or coact to sever the strip. 'That is, for'example, if the desired length passes between the cutter rolls during a series .of five will pass into' registry'and effect a out once ever five revolutions of the cutters.

Tl ie pulley 43 is secured at the front end of the shaft 50 which is journalled in the bearing structures 51 and 52 on the support ing framework 53 of the section C. Betweenthe bearing structures, the shaft supports the lower roll 47 of the cutting mechanism,the knife roll 46 being mounted on the shaft 53' journalled in the bearing structures 51 and 52 above the shaft 50. The cutter rolls are positively driven, the gear 54 on the shaft 50 meshing with the gear 55 on the knife roll shaft 53 (Fig. 5).

5 Below the shaft 50,'the shaft 56. is jour 53 and supports on nalled in the framework I I gear 57 which meshes with the gear 54 on the shaft 50. At its front end, the shaft 56 carries the gear 58 and also the sprocket pinion 59 (Figs. 4 and 5). {The sprocket pinion is connected byxthe chain 60 with the large sprocket 61'secured on the outer 'e d of mama j rnallerl in he the respective pulley disks.

revolutions thereof, the bars behind the cutting rolls,

the gears 54. and 57,

framework 53. The shaft 56 supports also the sprocket wheel 63 which is connected by the chain 64 with the sprocket 65 on the shaft 66 journalled over the guide-plate 45 in brackets 67 and 68 extending from the upper part of the framework. 53. Over the guide-plate 45, the shaft 66 supports the cylindrical brush 69 which engages with the tubular'strip of paper coming from unit A, and keeps this hand held flatly against the plate and also assists the feed rolls 22 and 23 in, propelling the paper to the cutting mechanism. The brush serves also to clean any surplus glue from the 'band'before it reaches the cutter mechanism.

. The tubular paper strip travels along the plate 45 and first passes between the cutter rolls and then on to the table 70 on the framework 53, the table being at a little lower level than the end of the plate 45 (Fig. 4).

.In accordance with my invention, the folded band is out into lengths L, which lengths are then transversely perforated or slitted so that they can be readily torn or separated into the wrappers or cartons W. The relative adjustment between the feed rolls 22 and 23 and the knife rolls is such that, after the proper length of folded strip has been fed throughthe cutter-rolls and onto the table 70, the cutter rolls will co-operate to cut the band, the folded band being this cut at regular intervals and into lengths which are then slitted or perforated transversely. The length of the cutoff sections can be adjusted by the variable speed mechanism. The feedrolls 22 and 23 are driven at a constant speed from the motor 30, but the speed of rotation of the cutter rolls is determined by the setting speed ofgthe cutter-rolls is increased, the interval of cutting will be shortened and the wrapper lengths will be shorter, while if the speed of the rolls is decreased, the interval between cutting is lengthened and the wrapper lengths will be correspondingly longer.

After a length has been cut from the folded band, it is placed in proper position on table 70 thereon.

tion of the length for thereon. At the front endof the ta le, just a kicker 72 projects a distance above the table 70 and travels in the slot 73 in the table. This kicker is carried at the u per end of a rod 74 which extends upwardly 'from'a cam-arm 75 pivoted onthe framework 53 at 76. At its outer end, the cam-arm has the cam-roller 77 which engages the cam 78 secured on the shaft 62. This shaft 62 is driven from the shaft 50 through the transmissiomtraincomprisin shaft 56, chain 60 an slprocket wheel 61, the cutter rolls being also r er f m the shaft 50. Just before each of the variable speed mechanism B. Ifthe preparatory to further operation At the end of said table, anadjustable stop 71 determines the proper posifurther 0 erationweight of the arm 75.

- brushes resist the movement length by the kicker 7 2 sufliciently to prevent cutting operation, front position close brushes 80 are suspended with their bristles in the path of t e severed strip. These of the severed buckling thereof or escape from the table but do not interfere with the positioning of 'the lengths against the stop 7-1. The brushes also hold the lengths flatly against the table in transit to the slitting mechanism. Kicker 72 leaves the inner-end of the length before the outer ends of the lengths engage the stop 71, to prevent buckling of the lengths. The parts of the slitting and corrugatin mechanism B are mounted on the framewor 81 adjacent to the framework 53 of the mechanism C of the machine. At'the front of the framework near the top thereof are the bearing structures 82 and 83 in which, are journalled the lower and upper shafts 84 and 85 on which are respectively secured the lower and upper cutting wheels 86 and 87. As shown in Fig. 8, the wheels have the cooperating cutting or shearing teeth 88 and 89 for cutting the short perforations or slits I 90 in the strip length. The cooperating cutting teeth are. in line with the table which is extended rearwardly to the slitting wheels (Fig. 5). There may be any number of sets of slitting wheels and spaced as desired, depending upon the number of wrappers in to which the lengths are to be divided.

For shifting the severed lengths from table'70 to the slitting wheels, I provide the chains or bands 91 which have propeller or- These chainsabutment teeth 92'thereon. (Figs. 5 and 8) travel around the front sprocket wheels 93 on shaft 94, and around the rear and lower sprocket wheels 95 and are on a.

96 respectively. The wheels 96 shaft 97 below the shaft 94'jandsupported on cross-beam 98 of the framework 53. Rear sprocket-wheels 95 are secured on a-shaft 99 which is journalled in the framework 81 behind the shaft 84' which carries the Flower slitting wheels. The end. of this shaft. 99 carries the sprocket-wheel 100 which is connected by chain 101 withthe sprocket wl 102 on the short shaft 103 Iwhichsupports the bevel" gear 104 meshing'with the gear 105 on the rear end of the shaft 50. The chains or belts 91 travel below the'transverse slots 106 provided in the table '70,

the upper ring. of the chains being parallel ieel with the table and the abutment teeth 92 projecting upwardly through the slots above the table-top to. enga e with the front edges of the severed lengt L arranged on the table bythe kicker 72. Each lengthis received at its front edge by the abutment teeth and shifted rearwardly on table 70 underneath the presser and. guide-fingers 107. The outer end of the length isflalso cngaged by the guide arm 108 which keeps ngths and retard the movement thereof to the other end of the length against the stop 1'08 areadjustably secured from a bar 109 secured to the framework 81 above the level of table 70, the fingers and arm-,being' clamped between the bar 109 and bar 110' secured-to the bar 109 by screws 111. Fingers 107 extend rearwardly between the slitting wheel sets and the lengths are carried between the fingers and the chains and presented to the slitting wheels which cut the transverse rows of slits in the lengths along which the lengths can be readily separated into wrappers or cartons W for containing the lamps or other objects to be wrapped or protected. After the slitting operation, the lengths are carried by the chains into position between the upper and lower crimping rolls 112 and 113 journalled on the framework 81 and yieldmgly held together by compression springs 11 t.

he mechanism for driving the slitting rolls and the crimping rolls is 'operated by a motor 115 mounted on the framework 81 of the machine-section D. The motor pinion 116 meshes with a gear 117 on the shaft 118, which shaft supports also a pinion 119 which meshes with the gear 120 on shaft 121, this 127 meshes with the gear 128 on the shaft '85 for the upper slitting wheels. The slitting wheels and crimper rolls are thus driven from and crim ed blanks are discharged from the machine lay the crimping rolls and may be received in a suitable receptacle or by a con veyor-belt (not shown) The lengths are readily ment. en they are to be used, they are separated alongrthe slit lines into the flat sectionswlnch can be readily opened for the shaft supporting also the pinion 122 which gear 127 secured on the Y shaft 84 'of the lowerslitting wheels.

It is usually desirable to have directions,

advertising matter, or other information printed on the individual wrappers, and the printing mechanism already referred to is provided for this pur ose. The printing mechanism is automatically operated and adjustable to print the paper band before folding thereo so that the printing matter will ap ear in proper position on thewraps before stated, any number of sets of slitting wheels may be provided, depending upon' the number and length of wrappers desired. The number of printing operations must therefore be the same as the number of wrapper sections. to each length. In other words, for each cutting operatlon there must be as many printing operations as there are wrapper sections for each length. Referring to Fig. 1, the printing roll 5 has the pulley 129 thereon whichis connected by the belt 130 with the pulley 131 on the shaft of the lower propelling roll 23 to frictionally drive the printing roll under control of an intermittently operated stop-device. On the printing roll are a number of sto -teeth 132 (Fig. 6) adapted to be engaged y a hooklever 133 which is pivoted intermediate its ends at 134. The lower end of the lever is connected by a rod 135 with the upper end of the lever 136 pivoted at its lower end at the inner end of the framework 1, a rod 137 connecting with said lever intermediate its ends and having at its other end the eccenwhich are supplied with ink by inking mechanism 143 (Fig. 2). By means of the eccen-.

tric mechanism and the connecting rods, the lever 133 isswung at the proper time to release the rinting roll so it will rotate one stepand is returned in time to receive the next tooth on the printing roll. When the roll revolves, it carries a printing plate .against the pa er band to print thereon, and when theroll is locked by the lever 133 the J. the ope printing paper an the belt 130 will slip over the pulley 129.-

lates are disengaged from x the during such locking of ,the roll The rods 1'37 and 135 are adjustable so that 'on "of-the lever 133 will be accu-,

readily crimpor corrugate the lengths, they In or rthat the crimping rolls can moreare preferably heated, and in Figs. 1 and 2 I show steam piping s for controlling the application of steam to the rolls for heating them.

The operation of the machine will be as follows: The paper band p is fed from the roll 3, first. through the gluing mechanism and then through the folding mechanism where the margins of the strip are folded over to the form shown in Fig. 10 with the overlapping edges glued together. The folded band is now' ironed down .between the rolls 22 and 23 and also propelled by said rolls along the guide-plate 45 and through the cutting rolls46 and 47 where, atproper intervals, lengths are successively cut from the stri and propelled by the kicker 72 on the table 70 against the stop 71. Chains 91 carry the successive lengths rearwardly underneath the spring fingers 107 and past the guide-arm 108, and through the sets of slittingwheels by which the length is slit transversely. The chains continue to carry the slitted length and feed it between the crim ing rolls where the len th is 1011 itudinal g g y corrugated and then e ected from the machine. When the lengths are separated along the slit lines, the resultin wrappers or cartons are ready for use, and are opened up for the insertion of lamps or other objects to be wrapped or protected. The machine is entirely automatic throughout inits operation, the paper band being fed in at one end and the finished wrapper lengths being delivered from the -machine, each wrapper section having the printing properly located thereon. Ad ustments on the machine can readily be made. By ad'ustin shaft 27, the spee of the cutting rolls and the lengths of the band sections cut ofi is adjusted. By arranging the slitting wheels, the lengths can be divided into any number of wrappers and by providing-the proper gears'58 and 141 the printin is'made to cor-H resppnd with the lengths an slitting adjustmen Y The invention .is not to be understood as restricted to the details set forth, since these may be modified within the scope of the a pended claims, without departing from to spirit and scope of the invention.
